Haploinsufficiency phenotype comments:

Van der Maarel et al. (1996) report a female patient with intellectual disability, scoliosis, slight facial asymmetry, clinodactyly and abdominal hypopigmentation who had an apparently balanced, de novo t(X;13)(q13;31) which disrupts ZMYM3. RT-PCR showed lack of normal transcript. The normal X chromosome was preferentially inactivated (PMID: 8817323).

The loss-of-function and triplosensitivity ratings for genes on the X chromosome are made in the context of a male genome to account for the effects of hemizygous duplications or nullizygous deletions. In contrast, disruption of some genes on the X chromosome causes male lethality and the ratings of dosage sensitivity instead take into account the phenotype in female individuals. Factors that may affect the severity of phenotypes associated with X-linked disorders include the presence of variable copies of the X chromosome (i.e. 47,XXY or 45,X) and skewed X-inactivation in females.
